drm_atomic_...rop_for_crtc(9)

💅 drm_atomic_set_mode_prop_for_crtc — Kernel API Manual ✨

okay so real talk, bestie, this is a page straight out of the Linux kernel API manual — like, the actual Kernel API Manual, no cap 🫶. The full name of the function is drm_atomic_set_mode_prop_for_crtc, and yeah the page header gets truncated to drm_atomic_...rop_for_crtc(9) because terminals are dramatic and love a cliffhanger 😭. Anyway. Sit down, grab a strawberry drink 🍓, and let's get into it.

🌸 NAME 🌸

drm_atomic_set_mode_prop_for_crtc — set the mode for a CRTC, but make it blob 💅

---

✨ SYNOPSIS ✨

int drm_atomic_set_mode_prop_for_crtc(struct drm_crtc_state *state,
                                      struct drm_property_blob *blob);

---

🎀 ARGUMENTS 🎀

• state — the CRTC whose incoming state we're updating. she's the main character here 👑
• blob — a pointer to the blob property to use for the mode. like, the vibe source 🌈

---

🦋 DESCRIPTION 🦋

So what she does is: she sets a mode on the CRTC state you want, and that mode originates from a blob property. iconic behavior, honestly.

The way this works is she takes a reference on the blob property for the CRTC state 💖 — and at the same time she releases the reference held on the state's existing mode property, if any was set. so it's giving responsible refcounting queen, no leaks, we stan 🧚✨

🔥 RETURN 🔥

• Zero on success 💚 (slay)
• An error code on failure 💀
• She cannot return -EDEADLK — literally not possible, don't even worry about it 🙈

bestie this whole page lives in ./drivers/gpu/drm — that's the directory, she's at home there 🏡

and that's the whole thing!! from your girl, dated October 2026, filed under the drm_atomic_...rop_for_crtc(9) header because some things in life are just truncated 💜 mwah, go set some modes 🎀✨
